Democratizing access to the world's most efficient protein source. From traditional wisdom to modern nutritional engineering.
We believe individuals and communities should have the knowledge and capability to produce their own complete protein. The industrial food system has created dependencies that leave us vulnerable to supply chain disruptions, price volatility, and nutritional compromises.
A spare room or basement can produce enough Wolffia to significantly supplement a family's protein needs—year-round, regardless of outdoor conditions.
The internet is full of "superfood" claims backed by marketing rather than evidence. We're committed to presenting only peer-reviewed research, clearly distinguishing between established facts and emerging hypotheses.
Every claim on this site can be traced to published studies, regulatory filings, or established agricultural science.
Home cultivation of food carries responsibilities. We emphasize HACCP principles, contamination control, and proper processing techniques because the alternative—foodborne illness or chronic toxicity—is unacceptable.
Our guides err on the side of caution. When in doubt, we recommend more stringent safety measures rather than less.
Wolffia represents a fundamental shift in how we think about agriculture. No soil. Minimal water. No pesticides. Vertical production in urban environments. The smallest flowering plant may hold the key to feeding a growing population without destroying the biosphere.
From traditional Southeast Asian food to modern superfood
Pre-1000 CE
Wolffia has been harvested and consumed in Thailand, Laos, and Myanmar for millennia. Known as "Khai-nam" (eggs of the water), it was collected from natural waterways and consumed as a vegetable, often in soups and curries.
18th-19th Century
European botanists first documented Wolffia during colonial expeditions to Southeast Asia. Initially classified within the Lemnaceae family, its unique characteristics—rootless structure, lack of oxalates—were noted but not fully understood.
1960s-1980s
Scientists investigated duckweeds (including Wolffia) for wastewater remediation. The plants' ability to rapidly absorb nutrients from water suggested potential for both environmental cleanup and biomass production. However, focus remained on animal feed applications.
1990s-2000s
Comprehensive nutritional studies revealed Wolffia's exceptional protein content and amino acid profile. The absence of calcium oxalate raphides—present in other duckweeds—was confirmed, establishing its unique safety for human consumption.
2014
Researchers at Bar-Ilan University identified bioavailable Vitamin B12 in Wolffia globosa—a groundbreaking finding, as B12 is virtually absent from plant sources. Unlike Spirulina's "pseudo-B12," Wolffia's cobalamin proved bioactive in human subjects.
2017
Hinoman Ltd. launched "Mankai"—a cultivated, standardized Wolffia globosa product. The brand name, derived from Japanese "manka" (full of energy), signaled the transition from wild-harvested curiosity to commercial superfood.
2018-2021
The landmark "Green Mediterranean Diet" studies (DIRECT PLUS) demonstrated Wolffia's benefits for glycemic control, liver health, and cardiovascular markers. Published in peer-reviewed journals, these trials established Wolffia as a legitimate functional food.
2018-2020
EU Novel Food approval for Wolffia globosa and Wolffia arrhiza confirmed their safety for human consumption. FDA GRAS status (GRN 742) followed, establishing regulatory frameworks for commercial distribution in the United States.
2020-Present
As commercial products became available, a parallel movement emerged: individuals growing Wolffia at home. The COVID-19 pandemic accelerated interest in food sovereignty, and the publication of home cultivation guides made DIY production accessible.
Understanding the legal and safety framework
In 2018, the European Food Safety Authority (EFSA) approved Wolffia globosa and Wolffia arrhiza as Novel Foods under Regulation (EU) 2015/2283.
Key requirements:
Wolffia globosa received Generally Recognized As Safe (GRAS) status under GRN 742 in 2018. This self-affirmed GRAS determination was based on:
For personal consumption, home growers are not subject to FDA inspection. However, adhering to Good Manufacturing Practices (GMP) principles provides:
Multiple safety studies support Wolffia's safety profile:
| Factor | Wolffia globosa | Lemna/Spirodela | Wild Duckweed |
|---|---|---|---|
| Calcium Oxalate | None detected | High (raphides) | Variable/Unknown |
| Regulatory Status | EU Novel Food, FDA GRAS | Not approved | Not approved |
| Consumption History | Centuries in SE Asia | None | Limited/None |
| Safety Data | Extensive | Limited | None |
| Human Consumption | ✓ Approved | ❌ Not recommended | ❌ Not recommended |
How we communicate about Wolffia
We cite peer-reviewed sources. We acknowledge uncertainties. We don't make claims that exceed the evidence. When we say something, you can trust we've verified it.
We disclose limitations. Wolffia is remarkable, but it's not magic. It won't cure diseases, replace medical treatment, or solve all nutritional needs. It's one powerful tool among many.
Scientific rigor doesn't require jargon. We explain complex concepts clearly, using analogies and visual aids. You shouldn't need a PhD to grow your own food.
Our goal is to make you self-sufficient. We teach principles, not just recipes. Once you understand the biology and engineering, you can adapt, troubleshoot, and innovate.
